Anyone Know John Wayne's Autograph Well? Is this Auto Photo from Vietnam Likely Good?

See the link below for the pics of the item. I have a color photo of John Wayne with a Navy UDT Seals unit from Vietnam. I am trying to determine if the inscription and auto are legit. Opinions requested please, TY.

In my opinion, the signed photo you have is no good. The slant and letter formation is done by a different hand.

My guess is it may be secretarial in nature, especially if the photo and ink appear as old in person as they do in the scan.
